Abstract: 346,562. Automatic stays for lids. DECCA GRAMOPHONE CO., Ltd. and COZENS, G. A., 1, Brixton Road, London. April 3, 1930, No. 10615. [Class 65 (i).] An automatic stay for the lid of a gramophone cabinet or the like comprises an arm 1, Fig. 3, pivoted at one end to the lid and sliding through guides 10 on a plate 8 pivoted to a bracket 6 in the cabinet. A detent 17, frictionally pivoted on the stay, engages, as the lid is raised, with a spring- controlled pawl 13, pivoted on the plate 8, and is moved over so that a slight lowering of the lid causes it to engage with a stop 12 on the plate to hold the lid raised ; in engaging with this stop the detent swings slightly and releases the pawl. Slight raising of the lid now brings the detent against a stop 11 to swing it clear of the stop 12, so that the lid can be lowered, the pawl 13 being pushed aside by the detent. In a modification, Fig. 9, the detent 17 is pivoted on the plate 8 and the pawl 13 on the stay. The pawl moves the detent under the stop 12 to support the lid, being released as before, and further raising of the lid causes the stop 11 to swing the detent clear, as shown.

Title: Process for shrinkproofing wool containing fabrics
Inventor: RUSSON WALLACE SIDNEY
IPC: D06M11/30

Abstract: Wool-containing fabrics are shrink-proofed by a process comprising (a) agitating them in an aqueous bath containing 20-30 parts of water to one part by weight of wool and 1-4% based on the weight of the wool of sodium bisulphite for 5-15 minutes at a pH of 2.7-4, (b) adding to the bath 2 2/3 -5\ba1/3 % based on the weight of the wool of a hypochlorite which is hypochlorous acid, an alkali metal hypochlorite or an alkaline earth metal hypochlorite, and agitating the fabrics in the bath for a further period of 4-6 minutes while maintaining the pH of the bath between 2.7 and 4, (c) adding - 2/3 -1\ba1/3 % based on the weight of the wool of the hypochlorite and agitating them for 4-6 minutes, (d) adding an additional 2/3 -1\ba1/3 % based on the weight of the wool of the hypochlorite and agitating for a further period of 4-6 minutes and (e) stopping the chlorination, preferably by adding 1-10% based on the weight of the wool of sodium bisulphite and agitating the bath for 15-45 minutes. The sodium bisulphite bath used in step (a) may also contain a non-ionic wetting agent and the pH may be adjusted by the addition of formic, oxalic, propionic, glacial acetic, monochloracetic or trichloracetic acid.  During the treatment with sodium bisulphite bath in step (a) the temperature may be maintained 56 DEG -60 DEG F., during the chlorination step at 56 DEG -62 DEG F. and during the step of stopping the chlorination at 60 DEG -70 DEG F.  After the step of stopping the chlorination the fabrics may be rinsed with water and treat treated with a cationic softener.  Fabrics containing wool alone or in admixture with cotton may be treated.  Specification 708,391 is referred to.
Patent GB-967045-A (GB)
Title: Arithmetic device
IPC: G06F7/505
Filed: 1963-03-18
Abstract: 967,045. Electric digital calculators. SPERRY RAND CORPORATION. March 18, 1963 [March 29, 1962], No. 10622/63. Heading G4A. A computer comprises two registers each capable of storing a plurality of multiple-bit operands and means for effecting parallel addition or subtraction of corresponding operands from the two registers. In the arrangement described, each register is capable of storing either one 36-bit operand or two 18-bit operands or three 12-bit operands. A 36-bit register 22 stores the augend(s) or minuend(s) and at the conclusion of operations, the result(s). A 36-bit register 20 stores the addend(s) or subtrahend(s). The computer control 10 is effective to gate the contents of the register 20 in direct or 1's complement form to a register 24 according as addition or subtraction is required. The contents of the registers 22, 24 are then applied to an " inverted half-subtract circuit" 32 which produces, for each corresponding pair of digits, an inverted bit difference which is stored in a register 34, and a borrow-bit which is stored in a register 36. For the fast determination of borrow-bits, a 36-bit machine word is divided into 6-bit groups. A circuit 42 (Fig. 9, not shown) comprising NOR gates is effective to determine whether a propagated borrow can be satisfied within a group, or must be propagated to the next group, or must be propagated as an end-around borrow, and if a borrow can be satisfied within a group, no "group borrow" signal is generated for that group. A further circuit 44 (Fig. 9, not shown) receives inputs from the inverted bit-difference register 34 and if all bits in any group of six bits are zero produces an output signal effective to cause any borrow from a previous group to be propagated directly to a subsequent group. Signals from the circuits 42, 44 are applied to further circuits 50, 52, 54 (Figs. 10a-d, not shown) comprising NOR gates, one of the circuits being selected at 76 by the control 10 according as one 36-bit, two 18-bit or three 12- bit operands are being operated upon. Signals representing the borrow bits are transmitted over paths 86 from the register 36 to a digit borrow tree circuit 84, Figs. 11a-c which is effective to provide for correctly propagated borrows and for any end-around borrows. The final arithmetic step is provided in circuit 90, (Figs. 11a-c, not shown) which functions as a half-subtractor to combine inverted-bit difference bits from the register 34 and borrow bits from the register 36 under the control of the output of the digit borrow tree 84. The output of the half-subtract circuit 90 is applied to the register 22 which has been previously set to all 1's by the control 10. The register 22 now contains the required result. The various circuits and registers which are described in detail in the Specification, comprise flipflops and NOR gates employing transistors.

Abstract: 1420263 Removing sulphur oxides by absorption UNION CARBIDE CORP 6 March 1973 [7 March 1972 12 Jan 1973] 10949/73 Heading B1L Sulphur dioxide is removed from gas mixtures containing it by countercurrent absorption at below 100C in an aqueous solvent comprising 50 to 95 percent of either  where R 1  R 2  and R 3  is alkylene C 2-4  and a b and c are integers of value 1 to 5 or wherein R 1 , R 2 , R 3  and R 4  is alkylene C 2-4 , R 5  is alkylene C 1-6  and a b c and d are integers from 1 to 5. The sulphite of the "trialkanolamine" may also be used. The absorbed sulphur dioxide is stripped from the solvent fed at under 115C to a stripping tower in which the lean bottoms solvent is kept below 125C and recycled to the absorber having been made up to an appropriate water/alkanolic composition. The solvent is also selective for sulphur trioxide but this is removed from the used absorbent by precipitation as sulphite using potassium ions.  The sulphur dioxide usually occurs in gas mixtures from fossil fuels and is present with SO 3  and carbon dioxide. It may occur with nitrogen oxides in which case they are removed also by precipitation with potassium. Thus a proportion of the lean bottoms is treated in each cycle to remove SO 3  and nitrogen oxides if they are present.
